“…As shown in figure 5 From the analysis of the above research results, it can be seen that when the PbO 2 reacts directly with FAI, there is only the yellow phase δ-FAPbI 3 obtained. This may be due to the by-product water molecule synthesized when the reaction between PbO 2 and FAI, can induce the growth of the yellow phase δ-FAPbI 3 [31]. However, when we add the appropriate amount of CsBr dopants in the reaction between PbO 2 and FAI, the growth of yellow phase δ-FAPbI 3 can be inhibited, thereby leading to the growth of black phase α-FAPbI 3 .…”

“…The electrolyte aqueous solution is composed of 0.1 M Pb (CH 3 COO) 2 , 0.1 M HNO 3 , 0.2 M NaNO 3 , and 0.05 M NaCl). Referring to our previous studies [31,32], the electrodeposition voltage is usually set as 1.5 V with a deposition time of 15 s. The thickness of the PbO 2 film is 177 ± 13 nm. After the PbO 2 film was deposited, it was immersed in the mixed FAI/ CsBr solution (25 * 25 cm weighing bottle) at room temperature, which contains 1 ml FAI/isopropanol solution (60 mg ml −1 ) with different amounts (5 μl, 20 μl, 40 μl, 80 μl) CsBr/methanol solution (8 mg ml −1 ).…”

“…For example, Huang et al acquired the MAPbI 3 film through the direct reaction between the electrodeposited PbO and spin-coated MAI, and the acquired MAPbI 3 solar cells display a high PCE of 14.59% [30]. Besides, the perovskite FAPbI 3 films can also be synthesized by the direct reaction of electrodeposited PbO 2 and spin-coated FAI [31,32], where the corresponding solar cells display an optimized PCE of 14.02%. From the abovementioned electrodeposition-based fabrication routes for perovskite solar cells, we can find that although there are some achievements have been obtained, it is apparent that electrodeposition methods for preparing perovskite solar cells are still a new emerging research field that requires deeper and systematic research to improve the efficiency of the perovskite solar cells.…”

The electrodeposition method has recently been developed for the fabrication of perovskite solar cells due to its potential advantages in commercial preparation. However, there is few studies on the preparation of perovskite solar cells by the electrodeposition method, especially on the perovskite FAPbI3-based solar cells. Herein, we fabricated the mixed perovskite FA1-yCsyPbBrxI3-x solar cells by an optimized electrodeposition method, in which the electrodeposited PbO2 reacts directly with FAI and an appropriate amount of CsBr dopants. The corresponding solar cells display the best PCE of 4.97%. By regulating the growth temperature in the reaction between PbO2 and FAI/CsBr, the efficiency of the mixed perovskite solar cells can be promoted to 10.18%. These results illustrate that the element doping and growth environment regulation can optimize the quality of the perovskite films, thus promoting the efficiency of the perovskite solar cells. With further optimizing the growth process in the electrodeposition method, it is expected to open up a new commercial preparation route for the perovskite solar cell in the near future.

“…In a similar vein, Li et al conducted research on this topic last year. [35] After the ED of PbO 2 , they sequentially spin-coated FAI/MACl or MABr/FAI solutions to form a mixed PK layer. Interestingly, the addition of MABr as a dopant was found to suppress the emergence of the 𝛿-FAPbI 3 phase, which plays a distinct role in the reaction between PbO 2 and FAI.…”

The active layer quality significantly impacts perovskite solar cell performances. In competition with the common spin, the electrodeposition (ED) method has emerged as a cost‐effective, scalable, and environmentally friendly alternative for perovskite deposition. This article combines an up‐to‐date critical review with experimental results for the development of perovskite photovoltaics. The first review section offers a critical understanding of the current state of the art for the processing of perovskite using an ED step. With the comparison of various methods described in the literature, the pros and cons of the technique are reviewed to assess its applicability at the industrial scale. The second part presents experimental findings from the authors, resulting from a 5‐year experience in this area. Various important and specific topics are covered including the optimization of the ED parameters, the influence of the substrate, the material's selection, the architecture, and the impact on active surface properties. The comparison of the performance data from the literature and the new set of experimental data allows to pace the way for the future development and the integration of stable, affordable, and large‐scale photovoltaics cells.

“…Lead-based perovskite nanocrystals are considered as one of the most sustainable materials for the development of new-generation solar cells. Solar cells prepared incorporating perovskite material possess ideal optoelectronic properties that helped achieving an impressive power conversion efficiency of 25.5%. − This performance of perovskite solar cells is higher than commercialized thin-film solar cells, such as silicon, GaAs, and Cu(In,Ga)Se 2 . − However, despite their great potential, a persistent threat on future use and commercialization is the issue of toxic lead-content − and longevity. − …”

Ruddlesden−Popper (RP) perovskite alloys have recently become attractive due to many desired physical properties originating from distinct van der Waalstype layered structures. In this work, a novel 2D RP-type Sr 3 Ti 2 S 7 perovskite material design is proposed by using first-principles calculations. Our results reveal that the 2D Sr 3 Ti 2 S 7 perovskite possesses dynamically stable structures, direct band structures with a band gap value of 0.86 eV, and a smaller effective mass (0.15/0.25 m 0 for electron/hole) than MAPbI 3 and phosphorene. More importantly, 2D Sr 3 Ti 2 S 7 possesses wide optical spectra (from infrared-to ultraviolet-light region) and a higher absorption coefficient (10 5 cm −1 ) than MAPbI 3 , silicon, and MoS 2 in the visible-light region. Interestingly, we also find that the ideal Dirac-like linear dispersion can appear near the Fermi level in the electronic band structures when compressive strain is applied. Especially, the Dirac-cone-like band structures can be realized when compressive strain is enhanced to −6%, indicating ultrahigh carrier mobility. These properties make the 2D Sr 3 Ti 2 S 7 perovskite a promising candidate for future applications in solar cells and optoelectronic devices.
